So, this is kinda similar to the other I helped you with:

<span>So r is the radius of the disk. The area is known and equal to 100Pi; so

100Pi = Pi r2

Now for r: r = 10

Circumference = 2 PI r = 20 Pi

I hope this helped!</span>

100Pi = Pi r2
r = 10
Circumference = 2 PI r = 20 Pi

The answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.
